CVClient, GameFrame

Well, it's actually called CaravaneerClient now, not CVClient. Turns out that naming a class CVClient inside a namespace CVClient is a bad idea, even though the language lets you do it. In any case, it's stubbed out to a fair degree of maturity. I'm now starting to rough out GameFrame, the command-line test tool that does integration testing from inside the Mono Solution. The hope is to have the server and client parts of the game all talking to each other, in a way suitable for batch-mode testing, all without having to touch Unity.
